Specification of Letters Patent.

Patented Mai'. 14, 1916.

Application filed June 18, 1914. Serial No. 845,916.

To all whom it may con cern Be it known that I, BARNEY H. SPENGLER, acitizen of the United States, residing at Los Angeles, in the county ofLos Angeles, State of California, have invented certain new and usefulImprovements in Steam- Injector Gil-Burners;y and I do hereby de- Clarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to oil burners, particularly to an oil burner inconjunction with a water leg and has for its object the provision of anovel oil burner in which means is provided whereby water is convertedinto steam by the burner, the steam being utilized for injection intothe burner nozzle to produce a blast.

An important object is the provision of a burner of this character inwhich the blast runs parallel with the water leg, whereby the directforce of the blast will not be concentrated at too limited an area uponthe water leg thereby increasing the length of life of the water leg.

Another important object is the provision of a burner of this characterin which the head of the water vaporizer and the water leg are formedintegral, thereby eliminating screw threaded connections or joints andproviding a construction which will be subject to only the minimum ofdeterioration caused by expansion andcontraction.

An additional object is the provision of an oil burner of this characterwhich will be simple, inexpensive in manufacture, efficient and durablein use and a general improvement of the art.

With these and other objects and advantages in view, the inventionconsists in the novel construction, arrangement and combination of partsas will be hereinafter more fully described and claimed, and illustratedin the accompanving drawing, in which,

Figure 1 is a side elevation of mv burner, Fig. 2 is a top plan viewthereof, Fig. 3 is a vertical sectional view, and Fig. 4 is a crosssectional view.

Referring more particularly to the drawing the numeral 5 designates theside wall of the casing of my novel burner which is in the form of anannular shell closed at one end by a head 6 and closed at the other endby a head 7 having a water leg 8 formed integrally thereon. The heads 6and 7 are securely clamped upon the shell 5 by longitudinally extendingbolts 9 provided with nuts 10. The shell is adapted to contain waterwhich should be preferably maintained at the level indicated at 11. 1norder that the height of the water may be kept constant, 1 provide ablock 12 extending through the head 6 at its lower portion and providedwith a valve seat 13 upon its outer end and also provided with threelongitudinally extending openings 14 and 15, the openings 11 beingdisposed oppositely and on each side of the central opening 15.

pipe 16 is threaded upon the outer end of the block 12 and has its outerend closed by a cap 17. A water inlet pipe 18 communi- Cates with thepipe 16. A valve stem 19 extends through the opening 15 in the block 12and has secured upon its outer end a valve 2O which is adapted to seatand unseat upon the valve seat 13. rFhe valve rod 19 extends into theshell 5 and is connected at its end to the short arm 21 of a bell cranklever 22 pivoted as at 23 upon a rigid bracket 24 and carrying upon itslong arm 25 a hollow ball or float 26. Vhen the water within the casingfalls below the level indicated at 11 the arm v21 will be moved towardthe head 6 and the valve 20 will be unseatecl, thus allowing water toflow through the openings 14: in the block 12 and into the casing.TvVhen the water reaches the level 11 the upward movement of the fioat26 and arm 25 will close the valve 2O and prevent the entrance of morewater.

In order that the water may be heated. 1 provide blast burners indicatedas a whole by the numeral 27 and comprising pipes 28 Communicating withthe shell 5 at its top, extending longitudinally of the shell upon itsexterior and terminating to the sides of and below the water leg 8. Oilfeed pipes 29 extend from any Suitable fuel reservoir (not shown) andhave their ends extending into the pipes 27 as shown at 30.

The operation of the device is as follows: Heat is first applied to thedevice by any desired means such as for instance a pan disposed belowthe device and containing a small amount of burning oil. or by means ofa blow torch or the like. Oil vapor passing from the burner members 27is lighted, whereupon the water contained within the shell 5 and waterleg Z3 will be heated. After the water has been heating for some time,steam will be generated within the shell and will pass out underpressure through the pipes 28. As the steam under pressure passes out ofthe burner members Q7 with the oil vapor, a powerful and effective blastwill be obtained, whereby the water within the shell will be rapidlyheated' and will produce the proper degree of pressure for maintaining`the maximum eiiiciency of the burner. The water leg 8 extends directlyinto a furnace fire box as will he understood. It will beV noted thatthe water leg' 8 is adapted to extend directly into a furnace and thatits diameter is such that a portion of the len' will be above the normalwater level in the casing 5. Bv this construction it will be obviousthat the water leg is substantially half filled with water and that thesteam generated therein readily returns to the casing'.

It will be readily understood that I reserve the right to make variouschanges in the form. construction and arrangement of parts withoutdeparting from the spirit of the invention cr limiting the scope of thesubjoined claim.

I-Iaving` claim:

In a steam generator, the combination of a casing having removableheads,l means, for feeding` water to said casing, a float operatthusdescribed my invention, I
